This drives me absolutely bonkers. I start off feeling boorish and uncultured, then I realize why, take a hearty dislike to the person on the other side of the terminal, think about other situations in which I have felt similarly awkward, and soon I’m pissed off about code-switching and class stratification. It’s not that I mind turning into a screaming Marxist, but really, the people who maintain Caltech’s email database should not be my prime ideological influences.
